Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as figure 1 As shown, the present invention uses an indium-gallium-nitrogen blue LED chip, is matched with an amber phosphor powder in a suitable proportion or an amber phosphor powder mixed with red and YAG yellow phosphor powder in a certain proportion, and is packaged into a new type of LED lamp, and the color temperature is controlled at 1700-2700K, and then configure free-form surface lens 2 in front of the LED, use aluminum substrate, ceramic substrate or metal circuit board, and heat pipe or heat dissipation fin, metal-based heat sink 6 to dissipate heat, with aluminum alloy or stainless steel shell 7 and controllable The constant current power drives the power supply 5 .

[0026] There is a lamp circuit board 4 inside the shell 7, and an amber high-power LED lamp 1 is welded on the lamp circuit board 4. The peak wavelength of the blue LED chip is about ...

Abstract

The invention discloses a low-color-temperature amber LED street lamp suitable for night driving of middle-aged and elderly people. The street lamp which is low in color temperature, still has the high lighting effect and the high color rendering performance of a light emitting diode, and has the high fog transmission characteristic of a high pressure sodium lamp is formed by combining a blue-light indium gallium nitrogen LED chip and amber fluorescent powder according to the appropriate proportion, and a traditional high-voltage sodium street lamp is replaced. Compared with the traditional high-voltage sodium lamp, the low-color-temperature amber LED street lamp has the high lighting effect and the high color rendering index; compared with a common white-light LED, the low-color-temperature amber LED street lamp has the low color temperature and the high fog transmission performance, internal clock disorders cannot be caused, caused light pollution is relatively low, and the low-color-temperature amber LED street lamp is suitable for night driving and night walking of the middle-aged and elderly people with the yellowed retina.

Description

technical field [0001] The invention relates to a high-power LED street lamp, in particular to an amber high-power low-color-temperature LED street lamp with a color temperature between 1700K and 2700K. Background technique [0002] With the development of semiconductor lighting technology, LED has the advantages of high luminous efficiency, multiple colors, orientation, energy saving and environmental protection, high reliability, good color rendering, long life, easy control, etc., and has emerged to replace various traditional lighting source products. trend. Compared with the traditional high-pressure sodium lamp street lamp, due to the small size of the LED, the lens can be used to meet the uniform distribution of light spots on the road surface and improve the utilization of light energy. Therefore, it can achieve higher light energy utilization and uniformity than high-pressure sodium lamps. ; Due to the high light efficiency of LED, it has better energ...
