Lamp temperature rise testing device capable of adjusting ambient environment temperature

Abstract

The invention discloses a lamp temperature rise testing device capable of adjusting ambient environment temperature. The testing device includes a constant temperature control system, a lamp test and power supply system and an anti-wind device. The constant temperature control system generates a high-temperature condition and an analog high-temperature condition through a constant temperature control circuit; the lamp test and power supply system provides a power supply line during a lamp test through a lamp test power supply circuit; and the anti-wind system prevents a lamp from convection influence of outside wind speed during the test of the lamp through an anti-wind device and prevents the device from influence of natural convection. The lamp temperature rise testing device capable of adjusting ambient environment temperature is low in cost, and is used in a lamp test occasion, the constant temperature control system can rapidly and efficiently provide or simulate any high-temperature condition, and the anti-wind device can provide windless conditions and convection conditions without natural influence which are required by testing.

Description

technical field [0001] The invention relates to a temperature rise test device of a product, in particular to a lamp temperature rise test device that can adjust the ambient temperature. Background technique [0002] In the past or traditional temperature rise test devices or test methods, the tested product is usually placed indoors or in a high and low temperature box for testing; indoor testing, in general, it is impossible to directly adjust a wide range of ambient temperature, It is also impossible to simulate the impact of using the product in the environment where the end customer is located; the test in the high and low temperature box, the method of constant temperature or temperature control of the high and low temperature box is generally the method of strong wind convection to control the temperature and constant temperature. In the environment of strong wind convection, the surface temperature of the product will be close to the temperature in the box, and it is...

Problems solved by technology

[0002] In the past or traditional temperature rise test device or test method, the tested product is usually placed indoors or placed in a high and low temperature box for testing; indoor testing, in general, cannot directly adjust a wide range of ambient temperatures, It is also impossible to simulate the impact caused by the use of the product in the environment where the end customer is located; the test in the high and low temperature box, the method of constant temperature or temperature control in the high and low temperature box is generally to use strong wind convection to control the temperature and constant temperature. If the product is placed in In a strong wind convection environment, the surface temperature of the product will be close to the temperature inside the box, and it is impossible to simulate the impact of the product in a windless environment where the end customer is located.
