Problems solved by technology
However, due to the low power of the LEDs used in this kind of lamps, they cannot be used as real main lighting. It is very unsuitable to use this kind of lamp on the stairs. First, the light distribution of this kind of lamp is not suitable for this occasion. The power is small, when installed in such a place that needs to achieve a certain illuminance, the result is a high-density installation, no matter it is an aesthetic angle or a practical installation angle, this kind of lamp is not suitable
Third, due to the use of low-power LEDs, the temperature of this light source will gradually increase when the light source is emitting light. When the temperature reaches a certain level, its operating voltage and light output intensity will be greatly affected. Impact
Therefore, the heat generated by the light must be evacuated to ensure the normal operation of the light source, otherwise it will lead to short life and low light efficiency. prone to personal safety accidents

Embodiment Construction
[0020] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] See figure 1 , the present invention specifically provides a recessed wall lamp 1 , which includes: a light-emitting substrate 2 , a conductive plate 3 and an outer shell 4 . For the specific structure of the light-emitting substrate 2, see figure 2 , wherein the light-emitting substrate 2 is in the shape of a cuboid, and four groups of hollowed-out cooling grooves 18 are arranged around the upper surface 5 of the light-emitting substrate 2, and a rectangular groove 6 for accommodating the light-emitting unit 7 is arranged in the middle of the light-emitting substrate 2, The depth of the rectangular groove 6 is smaller than the thickness of the light-emitting substrate 2 , and m*n light-emitting units 7 are arranged in a matrix in the rectangular groove 6 , where m and n are both integers greater than 0. Four corners of the light-...

The invention provides a wall-mounted lamp. According to the wall-mounted lamp, light spots of light sources are projected to form gradient trapezoid light spots by trapezoid prisms arranged in luminous units in a luminous substrate, so that light emitted by the light sources is distributed uniformly. In addition, the luminous substrate is provided with four groups of radiating grooves; radiating through holes are formed in a conduction plate, and a plurality of ventilating through holes are formed in a shell body, so that temperature can be reduced in a cross-ventilation mode effectively, the radiating area is reduced, and the luminous rate and service life of the light sources are ensured effectively; and by the design of light distribution and the design of the radiating of lamps, the functionality of major illumination is realized, the service life of the light sources is ensured, and market demands are met.
Description
technical field [0001] The invention relates to a high-power lamp, in particular to a high-power recessed wall lamp. Background technique [0002] Wall-mounted lights are also called wall-mounted lights in the field of lighting. They are often installed on walls, parks, gardens, and stairs in parks and squares. With the advancement of technology, a large number of low-power LED lights have been used as their lighting sources. , it has the advantages of emitting softer light, no radiation, low failure rate, convenient maintenance and low power consumption. However, due to the low power of the LEDs used in this kind of lamps, they cannot be used as real main lighting. It is very unsuitable to use this kind of lamp on the stairs. First, the light distribution of this kind of lamp is not suitable for this occasion. The power of the lamp is small, and when installed in such a place that needs to reach a certain illuminance, the result is a high-density installation, which is no...
